I sent 4 of the 5 projects, but I had doubts about whether my projects were being saved and approved since I copied my code directly in the Codepen each project had, without forking.
To confirm it in the fifth project I copied a random url in the solution and the project was approved. That means every url will be approved, no matter the tests.
Obviously then I will send the url of the real project. My question is if I will obtain the certificate once all the projects have been completed since with the previous ones I did not fork the Codepen provided by each project.
You are not required to fork the projects. You are not even required to do them on the suggested platform.
